Cosmetics container having a sealed structure

ABSTRACT

A cosmetics container having a sealed structure where an airtight state can be maintained inside the container by means of a simple structure, by using a configuration wherein the airtight state inside the container can be maintained by causing a sealing member to compress and spread out and to thereby attach hermetically to the inside of the body of the container and seal of the upper part of the body of the container as a result of downwards movement of a cap when one side of a lever member provided on the cap is pressed, and wherein the cap can be separated from the container by releasing the sealing member from the compression as a result of upwards movement of the cap when the other side of the lever member is pressed.

BACKGROUND

The present invention relates to a cosmetics container having a sealed structure, and in particular to a cosmetics container having a sealed structure wherein a sealing member is compressed and widened as a cap moves downward when pressing a portion of a lever member in a cap and comes into close contact with an inner portion of a container body for thereby closing the top of the container body and maintaining a sealed state of a container. When the other portion of the lever member is pressed, the cap moves upward, and the compressed state of the sealing member is decompressed, thus separating the cap from the container, whereby a sealed state of the container can be obtained by a simple structure.

A cosmetics container generally designed to contain cream, etc. is configured to be opened and closed as a lid is thread-engaged. The contents contained in the container can be used after the lid is removed from the cosmetics container. The lid can seal the cosmetics container since the lid is thread-engaged to the cosmetics container.

In the cosmetics container that is sealed since the lid is thread-engaged, a user needs to engage the lid to the container body by rotating the lid. In this case, the lid may not be well thread-engaged to the container body due to a user's mistake. If the lid is not tightly sealed, the contents contained in the container may leak out, so the contents may be spoiled.

It is urgent to develop a cosmetics container that can enhance a sealing ability on the basis of a simple structure.

FIG. 2 is a perspective view illustrating a construction of a cosmetics container having a sealed structure according to a preferred embodiment of the present invention. FIG. 3 is a cross sectional view illustrating a construction of a cosmetics container having a sealed structure according to a preferred embodiment of the present invention.

As shown in FIGS. 1 to 3, the cosmetics container having a sealed structure according to a preferred embodiment of the present invention comprises a container body 100 and a cap 200.

The top of the container body 100 is open to contain contents through. The cap 200 is engaged to the open top for thereby sealing the top of the container body 100.

In the inner portion of the top of the container body 100 is provided a mounting part 120 that extends in an inward direction, covering the inner circumferential surface of the container body 100, so that a lever member support body 230. At an end portion of the mounting part 120 is provided a content accommodation part 110 that extends in a downward direction for thereby containing contents.

In the present invention, a plurality of protrusions 130 are spaced apart at regular intervals, surrounding the inner circumferential surface, and are provided in top of the inner portion of the container body 100. Since a plurality of the protrusions 130 are spaced apart at regular intervals, pressure can be discharged via a space between the protrusions 130 in the course of the sealing work during which the cap 200 is engaged to the container body 100, so it is possible to prevent the developments of the pressure inside the container body 100.

The cap 200 is detachably engaged to the container body 100 and comprises a cover part 210, a sealing member 220, a lever member support body 230, a fixing plate 240 and a lever member 250.

The cover part 210 is configured to cover top of the container body 100. In the center of the top of the cover part 210 is provided a lever member engaging groove 211 for the sake of engagement of a lever member 250. In the bottom of the lever member engaging groove 211 is provided a through hole 212 for the sake of engagement with the lever member 250 as a rotational guide piece 235 passes through the through hole 212.

It is preferred that a rotation limiting shoulder 213 is provided in a portion of an inner circumferential surface of the lever member engaging groove 211 so as to limit the rotation of the lever member 250 when the lever member 250 rotates in a direction for the sake of sealing the container body 100.

The top of the sealing member 220 is engaged to the cover part 210, and the bottom of the same is fixedly supported by the lever member support body 230 and the fixing plate 240. The sealing member 220 is a cylindrical shape. In the bottom of the sealing member 220 is provided an extension part 221 that defines a hollow part 223 and extends in an inward direction. A fixing plate 240 is mounted in the extension part 221 so that it can be fixedly supported by means of the lever member support body 230 and the fixing plate 240.

In the extension part 221 are provided a plurality of engaging grooves 222 that are spaced apart at regular intervals in order for a protrusion piece 232, that will be described later, to pass through the same.

In the present invention, a lateral portion of the sealing member 220 is widened in an outward direction by means of an operation of the lever member 250 and is compressed against an inner circumferential surface of top of the container body 100 for thereby providing a sealing function. When the rotation guide piece 235 ascends, the lateral portion is widened in an outward direction and is compressed against an inner circumferential surface of the container body 100 for thereby providing a sealing function. When the rotation guide piece 235 descends, it returns to its initial state, and the sealing member 220 becomes spaced apart from an inner circumferential surface of the container body 100, and the compressed state is decompressed. It is preferred that the sealing member 220 is made from an elastic material so that it can be widened in an outward direction and then it returns to its initial state.

From the bottom of the sealing member 220, the lever member support body 230 is inserted in an engaging hole 222 and is configured to prevent any deformation of the sealing member 220 on the basis of an engagement with the fixing plate 240. The lever member support body 230 comprises a circular support plate 231 that mounts on the mounting part 120 of the container body 100, a plurality of protrusion pieces 232 that extend in an upward direction from the support plate 231 and that are inserted in the sealing member 220 and the fixing plate 240, a plurality of connection pins 234 that extend from an inner circumferential surface of the support plate 231 to a central portion, and a rotational guide piece 235 that is engaged to a pair of facing connection pieces 234 among the plurality of the connection pins 234 and that protrudes in an upward direction and supports the lever member 250 and guides the operations of the lever member 250.

In the present invention, in the lever member support body 230, the protrusion piece 232 is inserted in the engaging hole 241 of the fixing plate 240. When pressure is applied to the sealing member 220, any deformation of the sealing member 220 can be prevented. It is preferred that an engaging shoulder 233 is provided in the protrusion piece 232 so as to prevent the lever member support body 230 from disengaging from the engaging hole 222, 241.

In the top of the rotational guide piece 235 is provided a rotational guide protrusion 236 to which a lever member 250 is operatively engaged.

Inside the sealing member 220, the fixing plate 240 is engaged to the lever member support body 230 for thereby fixing the sealing member 220. In the central portion of the fixing plate 240 is provided a through hole 242 through which the rotational guide piece 235 passes. A plurality of engaging holes 241 that are spaced apart at regular intervals are provided in a portion coming into contact with the engaging hole 222 of the sealing member 220, wherein the protrusion piece 232 passes through the engaging hole 241.

The lever member 250 is engaged to the lever member engaging groove 211 of the cover part 210, the bottom of which lever member 250 is connected to the lever member support body 230, so it rotates when a user presses, whereby the interior of the container body 100 can be sealed with the aid of the sealing member 220. The lever member 250 comprises a pressing part 251, a sealing guide part 253 and a sealing guide protrusion 254.

The pressing part 251 is configured to rotate in a direction or in the other direction when the user presses it. The pressing part 251 comprises a protrusion engaging groove 252 for engagement to the rotational guide protrusion 236.

The sealing guide part 253 is engaged to the bottom of an inner portion of the pressing part 251 and is disposed between a pair of the rotational guide pieces 235 and is configured to rotate on the basis of the rotation of the pressing part 251 that rotates in one direction or in the other direction. It is preferred that the sealing guide part 253 has a semicircular cross section that prevents any interference with other components in the course of rotations.

The sealing guide protrusion 254 covers part of the sealing guide part 253 and comes into contact with or becomes spaced apart from the bottom of the lever member engaging groove 211 on the basis of the rotation of the sealing guide part 253 for thereby allowing the rotation guide piece 235 to ascend or descend. In the present invention, the sealing guide protrusion 254 is configured to contact with the bottom of the lever member engaging groove 211 when the pressing part 251 is in a horizontal state, so the rotational guide piece 235 can ascend as much as its thickness for thereby guiding the pressing of the sealing member 220.

When the sealing guide protrusion 254 comes into contact with the bottom of the lever member engaging groove 211, the rotational guide piece 235 ascends as much as its thickness, so the sealing member 220 is widened in an outward direction as it applies pressure to the sealing member 220. For this operation, the sealing member 220 comes into airtight close contact with the inner circumferential surface of the container body 100 on the basis of its sealing function. When it becomes spaced apart from the bottom of the lever member engaging groove 211, the rotational guide piece 235 descends as much as its thickness, and the pressure that has been applied to the sealing member 220 is removed, and the sealing member 220 returns to its initial state, so the container body 100 can be disengaged from the cap 200.

The sealing procedure of the cosmetics container having a sealed structure according to a preferred embodiment of the present invention will be described with reference to FIG. 4. FIG. 4 is a view for describing a sealing procedure of a cosmetics container having a sealed structure according to a preferred embodiment of the present invention. As shown in FIG. 4, in the sealing procedure of the cosmetics container having a sealed structure according to a preferred embodiment of the present invention, in an initial stage, in a state that the cap 200 is discharged from the container body 100, the cap 200 is engaged to the container body 100. At this time, the pressing part 251 of the lever member 250 remains oblique at a slanted angle, and the sealing member 220 is positioned spaced apart by a certain interval from the inner circumferential surface of the container body 100.

Next, when a user presses one end of the pressing part 251, the obliquely standing pressing part 251 starts rotating and becomes horizontal with the bottom of the lever member engaging groove 211. At this time, the sealing guide part 253 and the sealing guide protrusion 254 rotate together by the rotations of the pressing part 251. For this, the sealing guide protrusion 254 that remains spaced apart from the bottom of the lever member engaging groove 211 comes into contact with the bottom of the lever member engaging groove 211, so the rotational guide piece 235 can ascend as much as its thickness for thereby applying pressure to the sealing member 220.

When the pressure is applied to the sealing member in the above way, the sealing member 220 becomes widened in an outward direction, so the sealing member 220 comes into airtight contact with the inner circumferential surface of the container body 100 for thereby obtaining sealing functions.
